In this talk, I will first point out a few important applications that require radar cross-section (RCS) enhancement and then briefly review the existing RCS enhancement techniques. After that, we will consider the RCS enhancement of three objects: a thin plate, cylindrical objects and sphere. Physical principles will be explained for the RCS enhancement of each object. Simulation and measurement results are presented to demonstrate the effectiveness of the proposed RCS enhancement techniques. Some on-going research work on the topics will also be briefly introduced in the end.

Bio:

Zhongxiang Shen received the B. Eng. degree from the University of Electronic Science and Technology of China, Chengdu, China, in 1987, the M. S. degree from Southeast University, Nanjing, China, in 1990, and the PhD degree from the University of Waterloo, Waterloo, Ontario, Canada, in 1997, all in electrical engineering.

From 1990 to 1994, he was with Nanjing University of Aeronautics and Astronautics, China. He was with Com Dev Ltd., Cambridge, Canada, as an Advanced Member of Technical Staff in 1997. He spent six months each in 1998, first with the Gordon McKay Laboratory, Harvard University, Cambridge, MA, and then with the Radiation Laboratory, the University of Michigan, Ann Arbor, MI, as a Postdoctoral Fellow. In Jan. 1999, he joined Nanyang Technological University, Singapore, as an assistant professor, where he is currently a Full Professor in the School of Electrical and Electronic Engineering. Dr. Shen served as Chair of the IEEE MTT/AP Singapore Chapter in 2009. From Jan. 2010 to Aug. 2014, he was the Chair of IEEE AP-S Chapter Activities Committee. He is currently the Secretary of IEEE AP-S and an Associate Editor of the IEEE Transactions on Antennas and Propagation.

Dr. Shen is an IEEE Fellow. His research interests include design of small and planar antennas for various wireless communication systems, analysis and design of frequency-selective structures and absorbers, hybrid numerical techniques for modeling RF/microwave components and antennas. He has authored more than 180 journal papers (among them 100 were published in IEEE Journals) and also presented more than 160 conference papers.
